Abstract:

The MiniBooNE experiment has reported results from the analysis of electron-(anti)neutrino appearance searches, which show an excess of signal-like events at low reconstructed neutrino energies, with respect to the expected background. A significant component of this background comes from photon emission induced by (anti)neutrino neutral current interactions with nucleons and nuclei. These reactions also represent an irreducible background in electron-neutrino appearance measurements at the SK detector of T2K experiment. We have applied a microscopic model for single photon emission in neutral current interactions on nucleons and nuclei to determine the number and distributions of such events at the MiniBooNE and T2K experiments.
